ObjectiveThis study aimed to translate and validate of the Chinese version of the Occupational Low Back Pain Prevention Behaviors Questionnaire among clinical nurses.MethodsA total of 1,186 clinical nurses were recruited from three provinces in northeast China. The reliability of the translated questionnaire was measured by internal consistency, split-half reliability, and test-retest reliability. The validity of the translated questionnaire was evaluated by content validity index, exploratory factor analysis and confirmatory factor analysis.ResultsThe Cronbach's α value of the questionnaire was 0.891, and the coefficient values for the six domains ranged between 0.804 and 0.917. The split-half reliability and test-retest reliability were 0.663 and 0.734, respectively. Furthermore, the content validity index of the questionnaire was 0.938. The 6-factor structure, supported by the eigenvalues, total variance explained, and scree plot accounted for 63.038% of the total variance. In the confirmatory factor analysis, as the results of model fitting, χ2/df = 3.753, RMSEA = 0.048, GFI = 0.929, AGFI = 0.913, TLI = 0.934, IFI = 0.943, CFI = 0.943, PGFI = 0.759, PNFI = 0.807.ConclusionThe Chinese version of the Occupational Low Back Pain Prevention Behaviors Questionnaire had suitable reliability and validity among clinical nurses. Under the high prevalence of occupational low back pain, the questionnaire can provide a reference for developing educational intervention plans among clinical nurses.
